ICE3RBR0665JZ Application Note

This document is an engineering report of a universal input 12V 30W off-line flyback converter power supply utilizing F3R CoolSET™ ICE3RBR0665JZ. The application evaluation board is operated in Discontinuous Conduction Mode (DCM) and is running at 65 kHz switching frequency. It has a one output voltage with secondary side control regulation. It is especially suitable for small power supply such as DVD player, set-top box, game console, charger and auxiliary power of high power system, etc. The ICE3RBR0665JZ is the latest version of the CoolSET™. Besides having the basic features of the F3R CoolSET™ such as Active Burst Mode, propagation delay compensation, soft gate drive, auto restart protection for serious fault (Vcc over voltage protection, Vcc under voltage protection, over temperature, over-load, open loop and short opto-coupler), it also has the BiCMOS technology design, built-in soft start time, built-in and extendable blanking time, frequency jitter feature with built-in jitter period and external auto-restart enable, etc. The particular features needs to be stressed are the best in class low standby power and the good EMI performance.
